Multipathing configuration maximums for IBM Power Systems hosts
When you configure, keep in mind the maximum configuration for IBM® Power Systems™ AIX® hosts.
Table 1 provides the maximum volumes
and paths per volume for the subsystem device driver (SDD) and the subsystem device driver
path control module (SDDPCM).
Object | SDD maximum | SDDPCM maximum | Description |
---|---|---|---|
Volume (HDisk) | 512 | N/A | The maximum number of volumes that can be supported by the SDD (per host object). The maximum number of volumes is enforced by the Storwize® V3500 system. |
Paths per volume | 8 | N/A | The maximum number of paths to each volume. The number of paths directly corresponds with the resulting path-failover time. Although the maximum number of supported paths is eight, do not use more than two paths per adapter port. |
